GM diesel pickups first to undergo extra EPA, CARB testing

The effects of Volkswagen's long-running diesel emissions evasion are starting to spill over to other automakers, but General Motors is taking things in stride. The 2.8-liter, four-cylinder Duramax in the 2016 Chevrolet Colorado and GMC Canyon is the first engine to get extra scrutiny by the Environmental Protection Agency and the California Air Resources Board, Automotive News reports. Rather than just the usual in-lab test, it's also being checked on the road. However, the extra evaluation shouldn't have any impact on when the trucks with his mill hit dealers later this fall. "We're in our final stages of the EPA certification, and our launch is on track," Chevy spokesperson Otie McKinley tells Autoblog. The four-cylinder diesel in the trucks makes 181 horsepower and 369 pound-feet of torque, and the automaker is touting low NOx production. In the announcement for the Colorado's specs, the company calls it "the cleanest diesel truck engine ever produced by General Motors." The tech includes exhaust gas recirculation to lower combustion temperatures and improve emissions. There's also a urea tank like on the bigger diesels for full-size trucks, and it gets refilled in time with oil changes. An indication on the instrument panel lets drivers know when that's needed, too. Even with the more demanding testing, the company doesn't seem too worried about the four-cylinder passing. "Part of our development process is on-road and off-road [laboratory] testing," Scott Yackley, Chevy Trucks assistant chief engineer, said to Automotive News. In the wake of the VW scandal, the EPA has pledged more rigorous testing. Before, on-road emissions evaluations were largely limited to heavy-duty vehicles, but the agency has decided to apply the checks more often to other models. There's also now greater cooperation with Canadian authorities.

January no slump for Chevy Volt this year

The mild winter didn't tank January sales for the Chevy Volt this year. While last month's sales were a lot lower than December's – because January new vehicle sales are almost always lower than December's - the second-gen Volt had a good month. GM sold 996 Chevy Volts last month, an increase of 83.8 percent over the 542 sold last January. In December, 2,114 Volts were sold. The trend wasn't as good over at Nissan, which sold 755 Leafs in January. That's a drop of 29.4 percent compared to the 1,070 sold in January 2015. Given the lower overall sales for the Leaf these days, the drop from December wasn't as bad, with 1,347 Leafs sold in the last month of 2015. What's absolutely amazing is that after over five complete years of sales, the cumulative totals of the Leaf and Volt sales in the US remain almost exactly the same. The current difference is only 600 units, with the Leaf on top. If the Volt continues to outsell the Leaf for the next few months – and all indications are that that is likely, since Nissan is offering the first-gen model while Chevy has put out it much-improved second-gen - then we will soon get back to an equilibrium like we were at the end of February 2015, when the difference was just two units. As always, our more complete wrap up of all the green car sales in the US will be coming soon. Stay tuned. Related Video: News Source: Nissan, GM Green Chevrolet Nissan Electric ev sales
